Advantages of Plastic Injection Molding

Injection molding is useful in making components of large products that we use today. Ice trays, bottle caps, and bins are just some of the products that are made from injection molding which uses mold cavities where molten material is poured and solidified.

Glass, metals and thermoplastics are the materials that can be used for injection molding. Below we will look at plastics and how this material is the best in terms of cost and recyclability.

Plastic is a low cost alternative to expensive metal and glass. Plastic is known for its durability, rust resistance, and toughness despite its being low in density. If you use thermoplastic, it is possible to produce complex shapes at a much lower cost than any other material. Because it is pliable it can take on any shape and when it is cooled, the shape hardens. In order to reduce brittleness when plastic is exposed to very cold temperatures, additives are added. If you want to form other shapes from a finished product, you can just simply reheat it.

If you have to make plastic products by hand, what could be the result? We would be left with misshapen and structurally weak objects that wouldn’t last a day. Injection molding ensures precision in design and soundness in structure. Here are some of the advantages of this invaluable process.

Minimizing or eliminating scrap is one of the benefits of using injection molding because the cavities can only contain the amount of plastic that is needed. You benefit on money savings and lesser problems with waste management.

Other parts and components can be made from waste plastic. The quality of this waste plastic is the same as with virgin plastic. Therefore waste is minimized.

Injection molding labor cost is a lot lower than molding plastic by hand. Productivity is high with injection molding and it is faster to manufacture products.

There are little or no defects with injection molded plastics. The common defects for this type of molded plastic includes burrs, an uneven layer, blisters when raised bits produce a rough and uneven surface, voids, empty spaces on the surface. Defaced products are remade.

Though plastic is known to many as non-biodegradable, it is highly recyclable and plants can use discarded and unused plastic parts.

The injection molding process takes care of most of the work which makes the finishing time shorter. Labor cost and time is further reduced.

If metal and glass cannot be used in certain applications they use molded plastic products. It is on a regular basis that plastics are used in industries like automotive, oil, gas, and electronics.
